Segmented assembly construction method for large-span variable-curvature steel box girder
The invention relates to the technical field of building construction, and provides a large-span variable-curvature steel box girder segmented assembly construction method which comprises the following steps: S1, establishing a three-dimensional model of a steel box girder, and dividing the three-dimensional model of the steel box girder into a plurality of steel box girder segments to form a design drawing; s2, all steel box girder sections are manufactured in a factory according to a design drawing; s3, sleepers are installed on the transport vehicles, and the steel box girder segments are placed on the sleepers and then transported to a construction site; s4, a temporary supporting frame is built on the construction site, and the temporary supporting frame can position the steel box girder sections and limit lateral deviation of the steel box girder sections; s5, the steel box girder sections are hoisted on the temporary supporting frame, the transverse distance between every two adjacent steel box girder sections is adjusted to be within 10 mm through a chain hoist, and the longitudinal distance between every two adjacent steel box girder sections is adjusted to be within 10 mm through a jack; and S6, the two adjacent steel box girder sections are welded in sequence, and all the temporary supporting frames are dismantled after welding operation is completed.
本发明涉及建筑施工技术领域，提供了一种大跨度变曲率钢箱梁分段拼装施工方法，包括以下步骤：S1、建立钢箱梁的三维模型，将钢箱梁的三维模型分为多个钢箱梁节段，形成设计图纸；S2、根据设计图纸在工厂内制造出全部的钢箱梁节段；S3、在运输车辆上均安装枕木，将钢箱梁节段放置在枕木上后运输至施工现场；S4、在施工现场搭建临时支撑架，临时支撑架能够对钢箱梁节段进行定位并限制钢箱梁节段的侧向偏移；S5、将钢箱梁节段吊装在临时支撑架上，通过手动葫芦将两个相邻的钢箱梁节段的横向间距调整至10mm以内，通过千斤顶将两个相邻的钢箱梁节段的纵向间距调整至10mm以内；S6、依次焊接相邻的两个钢箱梁节段，焊接作业完成后拆除全部的临时支撑架。
